Dead of Winter Patch - New Equipment Guide

I had a bit of time on my hands, and I looked through the equipment list (filtered the equipment tab to show all). I have not had much luck in locating topics that state which equipment comes from where, but these are all the new equipment that was added in the last patch. I know the vast majority of this comes from the chests obtained from opening packs, but 30 (I think 31 actually) were added to the loot tables for the Frost Ring Arena. I wanted to get more people in on where to find each equipment piece. Can anyone confirm where each item comes from amongst the list below?
